Liver metastasis after OPSCC

Hi and welcome to our group. Keytruda and other similar drugs have been used for many cancers and found to do amazing work in many cases, particularly squamous cell head and neck cancers. Long term effects are still unknown however.
Although I am not a doctor, I have observed how the medical community, against their own better judgement, assume that any cancer occurring after an initial cancer must be a metastasis of that initial cancer. Often it is not. You should ask, “How do you know this is a metastasis of the original cancer?”
Have you had a biopsy of the liver? PET scans can show all manner of things which could or could not be cancer. My PET scan will show I have lung cancer, for the last twenty years. Biopsy will show scar tissue from frosted lung fifty years ago. And I had tonsil cancer between those events. My point is, let’s not investigate cures until we know what we are really dealing with.
After our cancer battle, we always believe everything else is cancer retuning. I for one will be the first to let you know when that thought subsides.
Let’s hope for the best. And if, if this liver spot is a cancer type that Keytruda or similar drugs can combat, then we can go down that street. Good luck.

Thanks. I have had a PET scan and a follow up MRI-CT with contrast to confirm. They seem certain that it is from my throat cancer.
